Bit the bullet and ordered a 3" Cat-Back kit for my truck! I went with a single 3" kit, no offense to anyone but the duals under the bumper are way too played out!!

FYI- Anyone looking for a mandrel bent catback for cheap, Summit Racing has their kits on sale right now for excellent prices! From what I hear, the kit is all Walker/Dynomax stuff.

Anyone else using a single 3" on their 5.4?

3" is a little big, unless your truck is modded. You might lose some torque with less back pressure, but it'll sound mean at least
